| 摘 要： | 传统研究一般通过测试织物表面的几何粗糙度和摩擦性能来预测粗糙感,而认知科学家发现,栅栏粗糙性的辨别取决于表面纹理波动曲线的谐波成分及纹理间距.为深入揭示织物粗糙感的形成机制,基于织物的表面形貌曲线,计算平均粗糙度,统计不同波动高度下的纹理间距,并采用傅里叶方法提取频域内谐波特征,比较分析这些特征值与粗糙感之间的关系.研究表明,织物的粗糙感差异取决于表面波动曲线频域内谐波的最高峰高度,而粗糙感不仅与平均粗糙度有关,也与表面纹理间距有关.

| Abstract: | Most scholars studied the physical properties for roughness sensation by a correlation analysis with the geometrical roughness and friction properties of fabric surface,whereas cognitive scientists proposed that identification and discriminability of surface roughness depended on the components of harmonic waves consisted of surface profiles and the inter-element distance.To explore the physical quality for fabric roughness sensation,from the surface profiles of fabric,the average roughness and inter-peak distance under different levels of amplitude is calculated,and the harmonic wave components is obtained by fast Fourier transform analysis,and then the correlation between these values with the resulting roughness sensation is compared.It is indicated that roughness sensation of fabric surfaces depends on the maximum amplitude of harmonic wave components,and fabric roughness sensation magnitude is related to both the inter-element distance of surface textures and the averaging geometrical roughness. |
